Colo-compare gets packet from primary_in@var{chardevid} and secondary_in@var{chardevid}, than compare primary packet with
secondary packet. If the packets are same, we will output primary
packet to outdev@var{chardevid}, else we will notify colo-frame
do checkpoint and send primary packet to outdev@var{chardevid}.
if it has the vnet_hdr_support flag, colo compare will send/recv packet with vnet_hdr_len.
In order to improve efficiency, we need to put the task of comparison
in another thread. If it has the vnet_hdr_support flag, colo compare
will send/recv packet with vnet_hdr_len.
we must use it with the help of filter-mirror and filter-redirector.
